socket.error: [Errno 111] Connection refused

[knoxcard]

I am almost there, but I get the following error when I execute:

python bump-fee.py 2010aa960b330022b2db175410b13530dc6bdd1a9b38071e55cdd45d96b51a64
socket.error: [Errno 111] Connection refused

I have RPC enabled too, but don't see a config file to enter the credentials. If that is in fact the issue.

I see the issue, in my bitcoin.conf file I have

txindex=1
prune=2000

It appears you cannot have prune and txindex enabled at the same time. You need to disable pruning and redownload the blockchain.
